2 Claims. -(c1. 129-16.?)

This invention has to do generally with slide holders.

' More particularly, this invention relates to, and

has for its chief object the provision as a new article of manufacture of, a holder especially adapted for safely and protectingly filing and storing glass slides, such as are employed for the preservation of mounted specimens, smears, and the like.

This invention has for a further object the provision of a holder of the type and for the purpose stated which is simple in structure, which may be readily and inexpensively manufactured, which is exceedingly durable, which may be compactly arranged in fiatwise abutment against a companion holder in a filing cabinet or the like, and which is most efficient in the performance of its intended functions.

And with the above and other objects in view, my invention resides in the novel features of form, construction, arrangement, and combination of parts presently described and pointed out in the claims.

In the accompanying drawing- Figure 1 is a perspective view of a slide holder constructed in accordance with and embodying my present invention;

Figure 2 is a transverse sectional view of the slide holder, taken approximately along the line 2-2, Figure 1; and

Figure 3 illustrates in longitudinal section a plurality of the slide holders in face-to-back compact slide-protecting and storing arrangement and association as in a filing or record cabinet or the like.

Referring now in more detail and by reference characters to the drawing, which illustrates a preferred embodiment of my invention, the holder includes a main or back wall in the form preferably of an oblong-rectangular section A con structed preferably of any suitable inexpensive relatively stifi or semi-rigid material, such, for instance, as light-weight cardboard or the like preferably, though not necessarily, provided along its upper longitudinal margin with an outwardly presented indicia-tab I.

Forming part of the holder, is a so-called skeleton rigid frame B molded or otherwise constructed of some suitable preferably transparent plastic material and preferably integrally comprising a bottom strip or wall 2, opposite parallel end strips or walls 3, 3, projecting at right angles from the same side or margin of the wall 2, and one or more parallel partition-strips 4 also projecting at right angles from the wall 2 intermediate the end walls 3, 3', the partitions 4 being spaced one from the other and from the end walls :3, 3, for the formation of slide-pockets, as presently more definitely appears. The base wall 2, end walls 3, 3, partitions 4 are generally of thesame thickness, so that the same fiushwise register on their respective front and rear faces. However, for purposes presently appearing, :each partition-strip 4' is undercut, as at a, 11, along its opposite margins and each end wall 3, 3', is undercut, as at I), along its respective inner margin from the wall 2 to, their free ends in the provision of slide-ways, as best seen in Figure 1.

The frame B, so molded and formed, is disposed upon its rear face fiatwise, and adhesively fixed permanently, upon the one or front face of the wall A, and it will be understood that the frame B is preferably so sized with respect to the wall A that the base or wall 2 and end walls 3, 3, register respectively with the lower longitudinal and opposite transverse or side margins of the wall or section A. Preferably, however, the frame end walls 3, 3', and partitions 4 are of reduced length with respect to the transverse width of the back wall A, as shown, and in association or combination with the wall B form open top and open face pockets, as at 5, for endwise conveniently receiving, holding, and storing microscope slides or the like C, the number of such pockets provided by each holder varying, of course, with the number of partitions 4 provided by th particular frame B.

In use, a microscope slide or plate C may with ease and facility be endwise inserted into any one of the pockets 5, and the holders arranged compactly, as shown in Figure 3, in a filing drawer, cabinet, or other suitable storage receptacle. By reference to Figure 3, it will be observed that the smooth rear face provided by the wall A of each respective holder extends across the outwardly presented face of the contiguous frame B in spaced relation to the pocketed slides C, a protective closure for each of the slidepockets 5 and its held slides C being thereby provided, and, while not here specifically shown, the wall A on its upper front face enabling the recording and visual display of matter pertinent to the respectively pocketed slides C.

- It may also be noted that the microscope slides C are usually of uniform size and thickness. Hence, a frame B of standard dimensions may be provided, so that the individual microscope slides C may be snugly held and stored in the pockets 5 provided by the frame B and wall A. It will, of course, be evident that, by varying the dimensions of the wall A and frame B, the holder may be readily adapted for the filing and storage of photographic plates or negatives, lantern slides, and other flat articles whose surfaces are to be protected from scratches or other such injury or breakage.

It should be understood that changes and modifications in the form, construction, arrangement, and combination of the several parts of the holder may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1. As a new article of manufacture, a slide holder including a synthetic plastic frame integrally comprising a base wall and a plurality of strips projecting from one side of said Wall and spaced one from the other, said frame having an outwardly presented uniplanar face for smooth sliding engagement with the rear face of a preceding slide-holder when the slide holders are stacked, each of the intermediate strips being undercut along its opposite side margins and each of the end strips being undercut along its inner margin, said frame being unflanged intermediate said strips in the provision of fiat bottom walls for engagement only with a transverse edge of the slide, and a section of cardboard adhesively fixed to, and upon a face of, the frame in the formation of a plurality of open-top slidereceiving pockets. I

2. A slide holder comprising a card-like wallmember and a pocket-forming frame of synthetic plastic material secured upon the face of the wall-member, said frame integrally comprising a bottom strip, opposite parallel end strips projecting at right angles therefrom, and a plurality of parallel partition strips also projecting at right angles from the bottom strip intermediate the end strips, said end strips being provided on their inner longitudinal margins and said partition strips being provided on both longitudinal margins with flanges for the formation of slide pockets, said bottom being unflanged intermediate the end and partition strips, the outer faces of the bottom strip, end strips, and partition strips being disposed in a single plane for flushwise engagement against the rear face of a preceding slide holder when a plurality of the slide .holders are stacked, thereby completely enclosing the slide pockets on the front, rear, bottom, and sides.
